* Detect double stacks in the new format in tests * Remove unnecessary uses of getStackByFiberInDevAndProd These all execute in the right execution context already. * Set the debug fiber around the cases that don't have an execution context * Remove stack detection in our console log overrides We never pass custom stacks as part of the args anymore. * Bonus: Don't append getStackAddendum to invariants We print component stacks for every error anyway so this is just duplicate information.
